Guest house, approximately 1,200 sqft, remodeled in 2023 with new HVAC and its own unobstructed San Francisco skyline and Golden Gate Bridge views. Tennis court, pool, spa, and pool house on level lawns: a built-in staycation. Six-car garage plus four-car carport for ten covered spaces, with generous guest parking. The second parcel provides lasting privacy and view protection. Minutes to downtown Tiburon and the Tiburon ferry, within the Reed Union School District.
